INTERNAL-COMBUSTION ENGINE.

Specification of Letters Patent.

Patented Feb. 29, 1916.

Application filed April 27, 1914. Serial No. 834,793.

To all whom it may concern a citizen of the United States, residing a Stockton, in the county of Books and State of Kansas, have invented certain new and useful Improvements in Internal-Combustion Engines, of which the following is a specification.

The invention relates to improvements in lubricating means for internal combustion engines.

The object of the present invention is to provide novel means for lubricating the cylinder which consists of a pump cylinder arranged beneath the main engine cylinder and having the piston thereof connected with the main piston rod so that oil is pumped into the auxiliary cylinder on the working stroke of the main piston and from thence to the piston rod which is connected with a passage to the main piston so that a reliable and expeditious lubrication is provided.

With reference to the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts: Figure 1 is a vertical sectional view taken through my improved engine, Fig. 2 is a detail fragmentary sectional view of the main piston showing the oil chambers therein and oil passage in the pis ton rod, Fig. 3 is a horizontal sectional view taken through the piston, and Fig. 4 is a detail horizontal sectional view of the piston rod taken on line 47% of Fig. 1.

Referring to the drawings by characters of reference the numeral 1 designates as an entirety an engine cylinder having inner and outer side and top walls 2 and 3 that are spaced from each other to provide a water jacket or chamber 4. To brace the walls 2 and 3 and provide a rigid structure spacing and blocks 5 are positioned between the inner and outer wall and may have fastening means not shown extended therethrough or be formed integral with one of the walls. A piston 6 having secured thereto a piston rod 7 is slidable within the cylinder 1. The outer or lower end of the piston rod 7 extends into an auxiliary pump cylinder 8 and has on its longer end a piston 9. A connecting rod 10 connects the lower end of the piston rod 7 with the crank shaft, not

plate 13.

shown. The bottom wall of the cylinder 1 comprises horizontal plates 11 and 12 that are spaced from each other and connected at their peripheries by a vertical flange or An annular lateral flange 14 is carried by the lower edges of the walls 2 and 3 and has an opening 15 formed therethrough so that the compartment or jacket 4: communicates with the compartment 16 formed by the arrangement of plates 11 and 12. A ring 16 is secured upon the under face of the lower plate 11 and surrounds the auxiliary pump cylinder 8. A ring 17 having a beveled inner face 18 is mounted within the jacket 16 between the plates 11 and 12 with its outer edge engaging the flange or wall 13. Bolts 19 are inserted through the flange 14, plates 11 and 12 and rings 16 and 17 to secure the beveled plates and rings to the main cylinder 1. Bolts 20 are inserted through the plates 11 and 12 and ring 17 adjacent the outer periphery thereof to provide a rigid structure. The piston rod 7 extends through central open ings in the plates 11 and 12. A packing sleeve or collar 21 is mounted within the openings in the plates 11 and 12 and receives the piston rod 7. Packing rings 22 are fitted within the bushing 21 and slidably receive the piston 7 so as to provide a tight joint and prevent leakage of oil or gas.

Suitable supporting blocks 23, preferably similar to the ones 5 are arranged within the jacket 16 between the plates 11 and 12. A water intake pipe 241 is inserted into the ring 17 within the jacket 16 and at its inner end communicates with a horizontal passage 25 that. in turn communicates with the jacket 16. It'will thus be seen that the water in being run into the jacket 16 will be forced around and about the cylinder from top to bottom and around thesides thereof. A suitable outlet port 26 is provided at the upper extremity of the cylinder 1 and may be suitably connected with the exhaust manifold by means of a pipe not shown. A spark plug receiving tube 27 is inserted through one side of the cylinder 1 adjacent to the lower edge thereof and is designed to receive a spark plug, not shown. An opening 28 is formed through the block 5 in the extreme uppermost part of the cylinder. This opening 28 communicates with the interior of the cylinder and the atmosphere and is designed to receive a spark plug not shown. It will thus be seen that I have provided a plug adjacent each end of the cylinder so that a charge may be fired upon either side of the piston 6 to provide a double acting engine. Exhaust ports 29 and 30 are arranged at the lower and upper portions of the cylinder 1 respectively and are arranged to communicate with exhaust valves not shown. Intake ports are arranged adjacent the upper and lower extremities respectively of the cylinder on the side thereof opposite to the ports 29 and 30. The ports 31 and 32 constitute pipes 33 that are inserted through the side of the cylinder and communicate with the interior of the cylinder and valve casings 34. Mounted in the valve casings 34 are valves 35 that are operated bysuitable rods 86 that are connected with the crank shaft of the engine after a manner not shown.

A. carbureter 37 having pipes 38 leading from each side thereof is connected by the pipes 38 to the casings 34 for the valves 85. The valves and casings 34 are arranged to alternately operate to provide firing on opposite sides of the piston 6. Valves similar to the ones 35 may be employed in connection with the exhaust ports 29 and 30 and in this connection it has not been thought necessary to illustrate the same. Rods 39 extend outwardly from the cylinder on the side thereof where the valves 35 are arranged and at their ends support vertical standards or rods 40 to the upper ends of which are pivoted rocker arms constituting one of the rods 36. A vertical reciprocatory rod 41 is connected with the outer ends of the rocker arms to provide for the opening and closing of the valves.

In 0 eration the char e is drawn into the uppe part of the cylinder through the port 31, when the piston is on its downward stroke and a charge in the lower end of the cylinder previously drawn in is compressed and upon the completion of the stroke fired and compresses the charge in the upper part of the cylinder which then fires forcing the piston downwardly drawing in a new charge through the valve 31 and causing the exhaust gases to be forced out of the exhaust port 29 at the bottom of the cylin der.

As a means for lubricating the piston 6 and the cylinder 1 I provide a longitudinal passage 42 in the piston rod'7 communicating by means of an opening 43 at the lower end of the piston rod 7 with the interior of the auxiliary pump cylinder 8. An oil intake pipe 44 is arranged upon one side of the-cylinder 8 and communicates therewith and a suitable source of oil supply. A check valve 45 is arranged within the pipe 44 and is designed to open to permit the oil to be drawn into the cylinder 8 when the piston rod is on its downward stroke.

Mounted within the oil intake pipe 44 is a transverse plate. or valve seat 46. The valve 45 -cooperates with the valve seat 46 upon the outer face of said seat and is provided with a stem 47 that is extended through a plate 48 in the pipe 44 and has a nut 49 adjustable upon its inner end. A spring 50 of the expansion type is mounted upon the stem 47 and is interposed between the nut 49 and plate 48. The spring 50 serves to normally hold the valve 45 in closed position.

The piston 6 is formed of two plates and 52 that are spaced from each other blocks arranged between the plates and 52 and secured in position by bolts that extend through the plates 51 and a and blocks 58. A suitable packing ring is provided for each of the plates comprising the piston 6. The plates in being spaced provide a chamber 56 to receive the oil. The piston rod 7 is extended through the plates 51 and 52 and is provided at its outer end with a suitable plug 57. A check valve 58 is mounted within that portion of the piston rod 7 that is disposed between the upper and lower edges of the piston 6 and cooperates with a seat 59 arranged in the passage 42. The valve 58 is provided with a stem 60 upon which is mounted an expansion spring61. The stem 60 is slidable through a guide plate 62 mounted within the passage 42. The oil in being forced upwardly through the passage 42 causes the valve 58 to open and allow oil to flow into the compartment or chamber 56 through an opening formed above the VHTXG and in one side of the piston rod 7. Suitable nuts (33 may be employed to secure the piston rod 7 to the piston 6. The oil in being confined within the space 56 is evenly distributed throughout the cylinder on the inner face thereof and the proper lubrication of the cylinder provided. When the piston rod 7 is on its downward stroke the piston 9 in the pump cylinder 8 is forced downwardly causing the valve 45 to open allowing a quantity of oil to flow into the cylinder 8. Upon the upward stroke of the piston 9 the oil within the cylinder 8 is forced through the opening 43 into the passage 42 and to the 'pistonG. The valve 45 is closed when the piston 9 moves upwardly.

It will be readily seen that I have provided a forced speed lubricating device that will lubricate the cylinder and pistons in a reliable and expeditious manner. The pis ton rod 7 is lubricated with relation to the bushing 21 by coming into contact with the oil that flows into the cylinder 8.

In practice, I have found that the form of my invention, illustrated in the drawings and referred to in the above description, as the preferred embodiment, is the most ethcient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as set forth.
